belong. It is more parallel than S. intricatus, and nearly as plane 

 as lucidulus, but it is easily distinguished from both by the deep 

 reticulation of the prothorax.

The habitat of this species is given in the Munich Catalogue as 

 Senegal, while Guerin-Meneville stated that it came from the Cape 

 of Good Hope. Not having at the time Guerin's work at my 

 disposal, and also misled by the wrong locality assigned to it in 

 the Catalogue, I described this species anew under the name of 

 S. rostratus, but having received an example alleged to have 

 been compared with Boheman's type of 8. modestus, I assumed 

 that it was the same species as that of this author, which it plainly 

 is not. 



The species, somewhat briefly described by Guerin-Meneville, 

 possess a character which is peculiar to S. modestus, i.e., " a straight 

 (? vertical) horn, bifid at the tip, and placed under the mentum." 

 The other South African species having a similar characteristic is 

 S. rixosus, Pering., but the tooth of the mentum is conical, not bifid, 

 and both species have a conspicuous elongated tubercle on the 

 frontal part of the head, which seems to have escaped the atten- 

 tion of Guerin-M6neville, for there is no reference to it in his 

 description. 



Eeiche, in Dejean's Catalogue, 3rd edit., 1837, mentions also this 

 species as Ateuchus jwoboscideus, Reiche, and gives its habitat as 

 " Cap. Bon. Sp.," but as M6neville in his description mentions that 

 the insect was communicated to him by Reiche, it follows that if 

 Reiche had mistaken the locality, the same mistake would be 

 made by Meneville, and no corroboration of the habitat could be 

 arrived at. But I find that " Ateuchus proboscideus, Reiche," figures 

 in the printed price-list of the insects collected by Drege in South 

 Africa, dated 1S11 (Preiz-Verzeichniss den lnsecten von C. Fr. Drege 

 in Siid-Afrika gesammelt., &c, Sept., 1841), and is priced higher than 

 any other South African species. This, I think, corroborates the 

 original locality. 



Mr. Alluaud described (Bull. Mas. d'llist. Natur. Paris, No. 4, 

 1902, p. 251) a new species from Madagascar (Scarabcms scvoistnt) 

 which has also a vertical tooth on the mentum.
